Well, it's the third time somekind of media is displayed to public that Nero is Vergil's son:

First in Captivate 2009, second time in Deadly Fortuna and now in an official artbook. If is not true, why should Capcom insist on the matter ? But we know too that even if it was said in game, people would refuse to accept.

Funny you mention Kamiya: people still insist he is the Word of God in DMC, when he doesn't only made DMC1 as a standalone game an he doesn't "accept" or recognized Lady or even Nero as DMC characters.He was only the Word of God in DMC1, a status that disappear when someone took over the series.
